Patented Jan. 7, 1941 UNITED STATES PRINTING MACHINE Blackwell K. Murchison, Brooklyn, N. -Y., assignor to Mastalign Corporation, New York, N. Y.,. a corporation of New York Application February 3,1939, Serial No. 254,372 21 Claims. (01.101 95) The invention relates to printing machines, and more particularly to a machine in which a single line of printing characters is set and an impression is made therefrom prior to the set- 5 ting of, and the making of an impression from, a succeeding line of printing characters, wherein means are provided to ensure accuracy and rapidity in the setting of succeeding letters in a line and in justifying each line prior to the making of an impression therefrom.

The present invention is an improvement in the printing machine shown in Letters Patent No. 2,145,271 granted to me under date of January 31, 1939. This machine comprises a plurality of type carrying members mounted upon a single rotary shaft, means being provided to rotate the shaft and the members to bring the desired types into the printing position, to lock each member after the proper type has been set,

and to disengage the shaft from each member after it has been set preparatory to the actuation of the succeeding type carrying members in setting up a line of type. This operation is repeated until the types for a line of the desired length have been set.

Following the setting up of each word, a justifying mechanism carried by each of the type carrying members is set, and after a complete line has been set, these various mechanisms are actuated to separate the discs to form spaces between words. The construction of the various parts is such that these spaces will all be equal but all will vary in width according to the number of letters and the number of words in a line.

With types arranged circumferentially about discs actuated by a shaft, the shaft must be turned to a variable extent to bring different types into the printing position, and since each disc carries a full font of type including upper and lower case letters, numbers, punctuation marks and other characters, the operator must proceed with extreme carein setting up each type in order to have the proper printing character brought to the printing position for making the impression, and must ascertain the exact number of words in each line in order to determine whether there will be adequate spacing of the words prior to the making of each impreswith. The actuation of the main shaft and the various discs is by hand, which tends to slow down the operation of the machine.

Upon the conclusion of the setting of the types of each word, the justifying mechanism carried 5 by the member having the last letter of a word is so actuated as to bring it to a position permitting the separation ofthe type carrying members to form the .spaces between the words after a complete line has been set. The mech- 10 anism for disengaging the setting bar and for engaging the locking bar with each type carrying member as it is set, has two succeeding operations, the main shaft between these operations being actuated when the justifying me'ch- 15 anism is to be set. This mode of operation required the use of one hand of the operator for actuating the setting and the locking bars, and required considerable acquired skill to develop a reasonable speed in the actuation of the ma- 20 chine.

Furthermore, in said machine the printing characters are arranged around the periphery of a hand wheel used in turning the main shaft, and the operator is required to closely watch this 25 hand wheel, as well as the copy being followed, to bring the proper letter or other printing character into the printing position. With printing characters positioned entirely about the periphery of the hand wheel, an unskilled operator may 30 turn the wheel throughout approximately 360 in searching for the right printing character, or impart greater movement to the wheel than is necessary. Either of these conditions may resuit from turning-the wheel in the wrong direc- 35 tio'n. The operator may also turn the wheel in the wrong direction, thus requiring greater movement of the wheel than is actually necessary to bring the desired letter into the printing position. This condition also tends to slow 40 down the operation of the machine, as does the necessity for referring to the proof sheet in order to determine the number of spaces required in a line of type which has been set.

With the above conditions in mind, I have pro- 45 vided in a machine of the type above referred to, a visual indicator mechanism independent of, but actuated from the-hand wheel for actuating the main shaft, which mechanism will not only show what printing character is in the printing position, but the quantity and direction of movement necessary to bring the succeeding character into that position with the least movement of the shaft. By providinga copy holder adjacent this indicator mechanism, the operator may at a glance determine whether the line will be I properly justified by the actuation of the justifying mechanism or whether there are too many letters in a line to permit the line to be completely filled out with adequate spacing between words. This spacer indicator shows at all times the members which have been set and hence may also be used by the operator to guide him in dividing words at the end of the line or using the type carrying members as quads for spacing purposes.

This mechanism is so constructed that it will be automatically actuated simultaneously with the turning of the shaft for setting the justifying mechanism of any type carrying member to indicate that the justifying mechanism of the member which has just been set has been'ac- .rtuated, but in addition to this will be actuated with each full actuation of the setting bar to indicate the last disc which has been set, Means are also provided to restore the spacing indicator to a normal or neutral position following the setting and justifying of each line of type or the making of an impression therefrom.

In addition to the indicators above referred to, I provide an electrically actuated mechanism for imparting the desired movement to the setting bar and the locking bar, as well as to the justifying mechanism indicator.

In a machine embodying the invention, the set type indicator is actuated by and in accordance with movements of the main shaft, while the spacing indicator, while actuated with each actuation of the setting bar, is normally inoperative to indicate the setting of the justifying mechanism of a type carrying member, but may be manually connected with the main shaft through the hand wheel, so that the actuating means of this indicator may be selectively actuated by a coupling mechanism adapted to beconnected with the hand wheel by one hand of the operator.

The mechanism for actuating the setting and the locking bars, and the actuating means for the spacing indicator is conveniently located adjacent the hand wheel, so that the mechanism may be tripped or set in motion within a wide range in the positioning of the hand in turning the wheel.

It has been found necessary to provide. an actuating mechanism for the setting and the locking bars which will operate substantially instantaneously, so as to avoid all those delays incidental to the disengagement of the hand with the setting wheel carried by the main shaft in order to actuate the said setting and said locking bars.

To accomplish this result, I provide electrical control members, and to adapt the machine to universal use, this mechanism is so constructed as to be adapted to either alternating or direct current.

In a machine embodying the invention, the

operator may use both hands in connection with hand wheels carried by the main shaft at opposite ends of the bank of type carrying members,

andmay actuate the setting and the locking bars and the spacing indicator without removing one hand from the main setting wheel, although movement of the hand along the wheel may be necessary when connecting the actuating means for the spacing indicator with the hand wheel.

The invention consists in the novel features of construction and combination of parts hereinafter set forth and described, and more particularly pointed out in the claims hereto appended.

Like numerals refer to like parts throughout the several views.

In the drawings, the frame of the machine is indicatedat I 0, the main shaft at II and the various type carrying members or discs at i2.

The shaft H is provided with keyways l3, in one of which the setting bar I4 is slidably mounted. The shaft II is turned by means of a hand wheel I5 having thereon printing characters I6 and having a sequence of edge notches l1, one for each printing character about the periphery of the hand wheel.

The various discs are provided with notches about the periphery thereof adapted to be engaged by a locking bar 18.

The setting bar l4 and the locking bar i8 are actuated by means of a sleeve i9 idly mounted upon the shaft ll so as to be adapted to be advanced along the shaft H with a step by step movement by the mechanisms, shown and described in my aforesaid Letters Patent. The manner of connecting the setting bar H with 'said sleeve is as shown and described in said patent. The said sleeve has movement imparted thereto along the shaft II by a rack actuated from a shaft 2| having a crank arm and handle 22. The means for imparting reverse movement to the sleeve i9 after an impression has been made from a line of type and before the printing characters have beendistributed, consists of a pull cord 23 and means actuated by a crank arm 24, also as shown and described in said Letters Patent.

The impression platen is shown at 25 and the paper feed cylinder associated therewith at 26. The movable header engaging one end of the bank of type carrying members is shown at 21, the fixed header at 28 and the rods forming a part of the stop mechanism for said movable 7.

in my aforesaid patent. The detailed constructype carrying member has been brought tothe tion of these mechanisms is immaterial to the present invention, and reference is had thereto and notto other parts of the machine of said patent, since an understanding of the present invention is possible without referring to such other details. i

The operation of the various mechanisms of the machine of the present application, except as to the mechanisms which are about to be described, is the same as in my aforesaid Letters Patent.

All of the mechanisms forming a part of the present invention have to do with the operation of the machine in setting a line of type and in justifying each line after it has been set.

In setting up a line of type, the various type carrying members 52 are turned by the shaft it until the desired printing character is in the printing position. The setting bar id is then disengaged from the member at the left of those engaged by it, and the locking bar engaged with that member. All discs, except the one at the left above referred to, remain connected with the shaft it so as to be rotatable therewith. Both the setting bar and the locking bar receive two impulses during the procedure of actuating each disc to set a type in the line to be printed. When the spacing of words is required, the mechanism used for justifying a line or type is set, the actual spacing of. words occurring as a result of movement of the shaft i t after a full line of type has been set. The setting of the justifying mechanism occurs between the two impulses incidental to the setting of the type carrying member, this mechanism being carried by the member carrying the last letter of a'word.

The turning of the shaft H, which may be in either direction, is a hand operation. There may be sixty or more of the type carrying members 42 in a bank which, together with the shaft ll, possess considerable weight. When the left hand alone is used in turning the shaft the operation of the machine of said Letters Patent, to secure the desired nice locating of the character to be printed, is slow and somewhat dimcult, particularly when, during the setting operation, a con-= siderable turning movement of the shaft is required, at which time the right hand of the operator is idle.

To increase the ease of operation of the machine in setting a line of type, I provide a second hand wheel 3i carried by the header 2?, so that the right hand may be mainly relied upon in turning the shaft, but both hands may be so used and may be kept in engagement with the two wheels 55 and 38 at all times while a line of type is being set. In this manner the speed of operation of the machine may be greatly increased.

In the event of a typographical error in setting a line of type, it is necessary to re-set the whole line, or that part of the line including the error. Hence, extreme care is required in operating the machine to prevent the making of an impression of any line in which a typographical error occurs, since this would result in the necessity for,

re-setting all the printed matter appearing upon the sheet at the time.

To permit an increased speed of operation in the machine and at the same time lessen the possibility of an improper actuation of any type carrying member, I provide what is herein termed a set indicator actuated by and in accordance with the movement of the hand wheel l5. This indicator shows the movement of the type carrying member being set and what letter upon that printing position.

As will more fully appear hereinafter, this mechanism also enables the operator to determine in which direction the shaft l I can be turned with the least quantity of movement required to bring a desired character into the printing position.

The set indicator comprises two gauge plates 32 and 33 having indicated thereon, printing characters corresponding with, and in the same spaced relation to each other as, the same printing characters carried by the members l2.

These gauge plates are spaced one from each other a distance to afiord clearance for a traveling tape 3 having indicia thereon adapted to register with the various characters upon one or the other plate 32 or 33. The characters upon the plate 32 correspond with those throughout 180 of each member 02, and those upon the plate 33 correspond with the characters about the remaining 180 of said members.

The indicia upon the tape 34, consisting of an arrow 35 pointing toward the plate 32, indicates what character upon this plate is in the printing position, while the indicia consisting of an arrow 36 pointing toward the plate 33, indicates what character upon this plate is in the printing position. These arrows are arranged upon the tape a distance apart equalling 180of the circumference of the various printing members.

The tape 35 is of substantially non-stretchable material such as steel. 4

Upon one of the plates as 32 is an arrow or other indicia 3? indicating a point of the periphery of the various members i2 at which no printing character occurs, so that the operator, prior to the making of an impression, can turn the shaft H in a manner to bring all members l2 which have not been used in setting the line of type, to a neutral position or one where no character is positioned in the printing line. This also permits the use of any of the printingmembers as a quad.

The tape 3 3 has a length substantially three times the circumference of the hand wheel l5, and in its run passes about various guide sheaves 38 defining the course of travel of the tape and also about the hand wheel I 5 from which it is driven.

One of the guide sheaves 38, adjacent the far end of the plates 32 and 33, is mounted in an adjustable bearing bracket 39 acted upon by an adjusting screw to by means of which any slack in the tape may be taken up to permit the accurate setting of the indicia 35 and 35 in relation to the printing characters upon the plates 32 and 33. There are three arrows 35 and three arrows 36 along the length of the tape spaced apart, as heretofore stated, a. distance equalling 180 of the circumference of the wheel E5.

The plates 32 and 33 are located at thetop of themachine within a clear field of vision of the operator and may have associated therewith a rack M for holding copy closely adjacent the plates. This permits the operator to follow the copy and follow the movement of the various type carrying members without giving any attention to any other of the mechanisms of the machine.

The location of the indicia 35 and 36 in relation to the characters upon the plates 32 and 33, and to a center line 42 upon each said plate, indicates to the operator the shortest amount and direction of movement of the shaft H necessary to bring a desired character into the printing line.

While the set indicator discloses what letter is brought into the printing position with each actution of the machine in setting a line of type, it does not indicate how many letters have already beenset in that line nor how many words are contained in the line. To meet this condition, I provide in the machine a justifying indicator mechanism which will register the number of letters which have been set up and the number of justifying mechanisms which have been set, and hence the number of letters and the number of spaces appearing in the line. This, mechanism, like the set indicator, is actuated from the hand wheel [5.

The justifyin indicator mechanism is within a clear line of vision of the operator, being positioned adjacent one end of the bank of type carrying members. This enables the same mechanism which actuates the setting bar and the locking bar to be used to operate said indicator mechanism.

No attention need be given the justifying indicator mechanism while an operator is setting a line of type. When the set-up of the line is almost completed, the operator may consult this indicator mechanism and see how many letters have been set and how many spaces will appear in the line, so as to permit accuracy in the seting of the final letters of the line and to permit the use of a quad or a justifying mechanism, or both, in bringing the last letter to the extreme end of the line.

In the embodiment of the invention shown in the accompanying drawings, this justifying indicator comprises a base 43 having a plurality of transverse grooves therein corresponding in number with the number of type carrying mem 40 bers l2. These grooves are spaced apart a distance equalling substantially one-half the thickness of the type carrying member, leaving an exposed space between the grooves of the same width as the grooves themselves.

Slidably mounted in each groove is a gauge slide 44 having one end thereof of a length to project beyond the base 43 toward the sleeve I9 and shaft II. This projecting end, as shown in Fig. 4, is positioned below the base.

50 The base 43 is provided with a longitudinal rib 45 having indicated thereon consecutive numbers, there being one number adjacent each gauge slide 44.

Pivotally mounted upon the sleeve i9, so as -to be movable with the setting bar [4, is an index finger 45 normally held by a spring 41 in engagement with the top of the base 43 in close abutting relation to the rib 45. The index finger 46 has movement with the sleeve l9 along the shaft ll, and at the same time is capable of movement toward and from the base 43.

Upon the under face of the index finger 46 is a cam 4-8 adapted to impart longitudinal movement to any gauge slide upon lifting of the index finger, although normally so formed as to permit movement of the index finger along the base plate without contacting with any gauge slide.

A stop screw 49 may be used to limit the oscillatory movement of the index finger by the spring 47.

Pivotally mounted upon the under side of the base 43 is a frame 50, the bar of which extends longitudinally of the base throughout substantially its full length, being positioned below and in operative relation to. the index finger 46,

along which this finger moves with movement I of the sleeve Hi. This frame is provided with a projecting end 52 by means of which the frame may be rocked with movement of the hand wheel II. The bar II is of a length to engage the index finger at any point of its movement along the base plate by said sleeve l9.

In the operation of the justifying indicator slides, means are provided adjacent the hand wheel ii for imparting rocking movement to the frame it whenever it becomes necessary in the operation of the machine to set a justifying mechanism carried by any disc.

This means, in the form of the invention shown, comprises a slide 53 mounted in a suitable slideway in a bracket 54 carriedby the frame of the machine. This slide is acted upon by a retract-.

ing spring '55 extending from adjacent the lower end of said slide to the said bracket. One end of this slide is provided with a tappet 56 extend ing over and adapted. toengage the projecting end 52 of the frame 50 when the slide is connected with and receives movement from the hand wheel I5. v

Carried by the bracket 54 and passing through a slot 51 in the slide 53 is a spring stud 58 en-. gaging said slide and having a normal tendency to hold it in engagement with the bracket 64, and to hold a lock tongue 59 carried by the slide out of engagement with 'the edge notches ll of the hand wheel l5.

As will more fully appear hereinafter, the justifying indicator mechanism is used during the setting of each line of type, and is restored to its normal, fully inoperative condition, following the setting of the line. As the justifying mechanism of any type carrying member is set, the movement of parts necessary to set this mechanism will impart movement to the index finger 46 in a manner to cause the cam 48 thereon to force a gauge slide 44 out of alinement with the other gauge slides and thus indicate that on certain discs the justifying mechanism has been set.

Upon the base 43 opposite to the edge thereof along which the index finger 46 travels, is a restoring bar 60 mounted for right line movement upon links 6| and 62. Acting upon said restoring bar is a spring 63 normally holding it outwardly of said base 43 and out of engagement with any of the gauge slides 44.

The link 6| is provided with an actuating arm 64 adapted to be engaged by a pin 65 carried by the sleeve l9 when said sleeve has received its maximum movement along the shaft II, this arm 64 having a thumb piece 65 permitting manual movement of the restoring bar.

It will be observed that the actuation of a gauge slide and the actuation of the set indicator tape 34 is, in each instance, by the hand wheel Hi. The set indicator does not in any way inform the operator of the number of letters which have been set, or the number of spaces which have been provided for by the setting of justifying mechanisms of different discs. The justifying indicator is actuated each time that the tape 34 receives movement, and thus registers the number of letters which have been set and the number of type carrying members upon which the justifying mechanisms have been set. Hence, by combining in the same machine these two mechanisms operated simultaneously and from the same source, the exact working conditions in and about the machine in setting a line of type are indicated to the operator at all times.

The tongue 59 of the slide 53 may be selectively engaged with any notch I1 of the hand wheel I5, and thereafter with the turning of this wheel away from the operator, the frame 58 is rocked in a manner to actuate the index finger 48 and its cam 48 in a manner to impart movement to the gauge slide 44 opposite which it may be at the moment. This mode of operation will. be more fully described later. I

To permit increased speed in the operation of a machine, it is desirable to provide motor actuated means, the control mechanism of which is conveniently accessible to the left hand of the operator, grasping the hand wheel I5, for actuating the sleeve I9, and with it the setting and locking bars operatively connected therewith.

This control mechanism and the source of power, the application of which to the mechine is determined by the actuation thereof, will now be described.

The power for actuating the setting and the locking bars and the justifying indicator is derived from a motor 61 through a speed reducing mechanism 68, both of well known construction. The power of said motor and said mechanism is applied to a driving shaft 89 carrying a flywheel 18. Said motor, while the machine is in use, is in continuous operation.

Associated with said driving shaft 89 is a driven shaft 1I adapted to be connected therewith by a clutch mechanism similar to that commonly used in an ordinary punch press.

Carried by the shaft 1| isa crank 12 connected by a link 13, having a spring 14 in the length thereof, with the crank of the handle 22.

The clutch mechanism above referred to includes therein a clutch pin or dog 15 having a slot 15a adapted to enter one of two clutch sockets 16 in the flywheel 18, said pin being acted upon by a spring 11 adapted to normally thrust said clutch member outwardly of the driven shaft into engagement with a clutch socket 16. The action of the spring 11 is restrained by means of a pivotal arm 18 having a cam surface 19 thereon adapted to enter the slot 150, said arm being adapted to enter a channel 88 of a collar carried by the driven shaft. The arm 18 is normally positioned in a channel 88 in a housing 8| carrying the clutch so as to prevent movement of the pin or dog 15 toward the flywheel 18.

During the operation of the machine, the clutch mechanism for connecting the driving shaft 89 with the driven shaft 1I must be set twice with the setting of each type carrying member I2 without regular intervals between the actuation of the clutch, and the actuating means for the clutch must 'be of a nature limiting the operative moment of the crank 12 to one full revolution without possibility of failure of the release of the clutch, irrespective of continued actuation of the control mechanism for causing setting of the clutch. While the speed of the driving shaft is not critical, in the formof the invention shown it turns at the rate of approximately one hundred revolutions per minute. Consequently the clutch must be set and also released within a fractional part of asecond, and no timing factor as to the actuation of the manually operative control mechanism is requiredto accomplish this result.

The actuating means for the arm 18 consists of a solenoid 82, the core 83 of which is connected with the arm 18 by a link 84. The circuit to the solenoid 82 is controlled by an electrical relay system, such as that shown in Fig. 9 of the drawings, and by a manually operative switch'mechanism consisting of a fixed contact member 85 mounted adjacent the wheel I 5, and a movable contact member 88 carried by an arm 81 having a segmental end 88 overlaying and extending the switch' mechanism extremely sensitive to the touch of the operator.

Leading from the source for actuating the solenoid 82 are wires 98 and 9| controlled by a main switch mechanism 92. This source may either be of alternating current or direct current.

A wire 93 leads from one side of thesource to one of the contacts 85 of the switch mechanism 85-86, and a wire 94 leads from the other con' tact of said switch to a winding 95 of the solenoid of arelay mechanism. Leading from the solenoid 95 is a wire 98 to the other side of the line 989I.

The solenoid 95 actuates two contacts 91 and 98, connected in parallel, simultaneously with the energizing of said solenoid, to close a circuit through wires 99 and I88, contact I8I and wire I82 to the winding of the solenoid 82.

Arranged in this line is a resistance element I83 for use when using a direct current source, and in shunt with this resistance is a switch mechanism I84 for use when using an alternating current source.

The switch'mechanism 91 is normally open. The switch mechanism I8I is normally closed.

Actuated by the core of the solenoid 82 is a switch mechanism I85, the contacts of which are arranged in a line I86, one branch of which leads to the winding I81 of a solenoid of a circuit interrupter switch mechanism including the contact I8I and a holding circuit including a second contact I88 actuated by the solenoid I81 and connected by a line I89 with the contact member 88. The circuit to the solenoid I81 is closed through a wire II8 connected with the wire I88 and a wire III connected with the wire 96.

Connected across the switch I8I from the wire I88 to the wire I82 is a spark suppressor consisting of a condenser H2.

The operationof the herein described printing machine is substantially as follows:

The operator of the machine, when bringing a printing character into the printing position, uses both hands in turning the shaft II, one upon the wheel I5 and the other upon the wheel 3|. All type carrying members I2 which have not been brought with a character into the printing position areturned with the shaft.

As the shaft is turned, lineal traverse is imparted to the tape 34 in relation to the plates 32 and 33 until the arrow 35 or 36 indicates what letter or character is in the printing position upon the disc being set and all other discs having movement with the shaft.

When beginning to set up a line of'type, the arrow 35 will be in register with the arrow 31, indicating that none of the discs is so positioned as to have any printing character in the printing least quantity of turning movement of the shaft I I which will suflice to bring a required character into the printing line.

Each plate 32 and 33 is of a length to corre-, spond with 180 of turning movement of the shaft.

With the conditions as shown in Fig. 1, if the next letter to be set is o", or the third letter beyond the blank space upon each disc indicated by the arrow 31, the operator knows that the shaft may be turned only a distance corresponding with the space of three letters upon the disc, and that the disc must have contra-clockwise movement from the left of the machine. If the letter required should be "u", then the operator knows that a clockwise movement, corresponding in length with the space occupied by four letters, must be imparted to the shaft.

Since the arrows 35 and 36 are spaced apart a distance equalling 180 in arc of the disc, it is obvious that the first letter upon the plate 32 and the first letter upon the plate 33 will be positioned upon the disc diametrically opposite each other.

With the use of the tape 34, the operator may rapidly turn the shaft either clockwise or contraclockwise, and the arrows upon the tape, with its movement by the hand wheel I5, permit the operator to follow the movement of the wheel and of the discs by watching the tape, so that no difficulty may be experienced in accurately turning the shaft and stopping its movement in setting each letter. The tape also permits accuracy in the stoppage of the shaft II so as to ensure a proper positioning of the various mechanisms in the machine to lock each disc in the set position.

While the proofing mechanism described in my aforesaid Letters Patent may be used, if desired, the tape 34 acts as a proofing mechanism as to each letter as it is set.

While with the use of a steel tape there is little likelihood of stretch of the tape, I provide the adjusting mechanism 3840, acting upon one of the guide rollers 38, to permit correction of any slight loss of adjustment in the tape due to stretch or slight inaccuracy in the length of the tape itself.

By providing a proof holder immediately above the plates 32 and 33, an operator may conveniently follow the copy and the tape 34 at the 1y of the shaft II.

same time, and, in operating the machine, is required merely to use the eyes in following the copy and the tape.

After each letter has been set, it is necessary to actuate the setting bar I4 and the locking bar I8 by imparting movement to the sleeve I8 axial- The mechanism used for imparting movement to the sleeve I8 through the shaft M and its crank arm 22 is as shown in my aforesaid Letters Patent. The herein described machine accomplishes this result by means of power instead of by hand, registers the number of movements of the sleeve during the setting of a line of type, and incidentally registers the number of justifying mechanisms which have been set during that period. a

After a letter has been set, the operator merely touches the overhang 88 of the lever 81 carrying the movable switchmember 88, thus engaging the contacts 85 and 86 and closing the circuit through the controlling relay mechanism to the solenoid 82.

Withthe energizing of the winding of this solenoid, movement of its core will raise the arm I8 ing the crank arm 22 and imparting movement to the sleeve I3 equal to one-half the thickness of a disc l2.

With movement of this sleeve, the index finger 48 will move along the base 43 from a position on one side of a gauge slide 44 into alinement with that slide. The cam 48, by this movement, will be positioned below the slide and the finger 48 above the slide.

The construction of the control relay mecha nism is such that irrespective of the length of time during which the contacts 85 and 86 are engaged, the clutch member I5 will be disengaged by the cam surface I8 from the flywheel of the driving shaft, upon the completion of one full revolution of said shaft. The action of the control relay mechanism securing this result will be more fully described hereinafter.

It is to be noted, however, that while the engagement of the contacts 85 and 86 is necessary to energize the solenoid 82, the de-energizing of this solenoid occurs irrespective of the continued engagement of said contacts. Hence, with each engagement of the contacts 85 and 88, the operation of the crank 22 and the mechanisms actuated thereby is limited to a single actuation.

The spring I4 in the length of the link 13 is merely for the purpose of providing a yieldable connection between the crank 22 and the crank 12 so as to avoid any extreme nicety in the construction and setting of these parts.

If, when a letter has been set, no spacing is required after the letter, the operator merely actuates the switch member 81 a second time, causing a repetition of the operation above described and a second movement of the setting and the locking bars to ensure further movement of the setting bar out of engagement with the justifying mechanism carried by the disc which has just been set. With this second movement of the sleeve I8, and two such movements are required with the setting of each disc, the index finger 46 again moves along the base 43, and the cam 48 carried by said finger moves out of engaging relation with the slide opposite which it was positioned with the first movement of the sleeve I8. The index finger 46 with this movement will indicate that the first disc has already been set and that the justifying mechanism of that disc has not been set.

These operations are repeated until a word has been completely set up, and the presence of a space between the last letter set and the next letter set is required.

When bringing the last printing character of a word into the printing line, the operation will be as heretofore described, up to the first actuation of the sleeve I8. After the operator has engaged the contacts 85 and 86, resulting in this first actuation of the sleeve I8, he engages the tongue 58 of the slide 53 with one of the notches I! in the edge of the wheel I5 by pressing said slide toward the wheel I5 against the tension of the spring 55. When said tongue 58 is thus engaged with the wheel I5, said wheel is given a contraclockwise movement, thus bringing the tappet 56 into engagement with the extension 52 of the frame 58 and rocking this frame in a manner to cause the bar 5| thereof, irrespective of the position of'the index finger 86 in relation to the base 43, to raise this finger. Since the first actuation of the sleeve I9 during the setting of each disc positions the cam 48 below and in opk erative relation to a slide M, this movement of" the index finger against the tension of its spring 41 will move the. slide 44 transversely of the base 43 so as to project the far end thereof beyond the adjacent slides. This indicates that the justifying mechanism upon the disc which has just been set, has been set to cause the formation of a space when a line has been completely. set and Justification of that line is required.

The movable switch member 8'l88 is then actuated to impart the second impulse to the setting and the locking bars.

The manner ofmounting the frame 50 is such as to limit the movement of the wheel in a manner to always ensure one of the notches about the succeeding disc I2 being 'in the proper operative relation to the locking bar.

Immediately upon the stoppage of the wheel I5, the spring 58 acts to disengage the tongue 59 from the notch I1 with which it is engaged, thus permitting the spring 55 to impart a return movement to the slide 53 and move the tappet 56 out of engaging relation wit-h the end 52 of the frame. To permit this mode of operation, the arrangement is such that the slide 53 has movement with the wheel I5 against the tension of said spring 55, and it is this movement of the slide with the wheel which causes the actuation of the frame 50.

After the second actuation of the sleeve I9 incidental to the setting of a letter and of the justifying mechanism of the disc carrying that letter, the wheel I5 is free to be turned in setting the desired letter upon the succeeding disc, since the spring 41, with the disengagement of the tappet 56 with the extension 52, causes downward movement of the index finger 46 as well as of the frame 50, so as to again position the cam 48 below the plane occupied by the various slides 48.

As the index finger 46 is advanced along the base 38 with a step by step movement in the manner above referred to, it will apprise the operator of the number of letters which have been brought into the printing line and-the number of justifying mechanisms which have been set. When the setting of the type approaches the end of a line, the operator, by glancing at the index finger and the various slides Ml which have been displaced during the setting of the line, may estimate what space is available for further letters toward the end of the line. Hence, if necessary, the operator may actuate the movable contact 86 twice in rapid succession and thus set a quad in the line after turning the shaft so that the arrow 36 is opposite the arrow 51.

After a line has been completely set, whether it be a full line or a partial line, the various justifying mechanisms are actuated in the manner described in my aforesaid Letters Patent, an imprintis made, and the above operations are proceeded with in connection with the next line of type to be set.

After the impression has been made, the bar 60 has a. parallel movement imparted thereto by the lever 64, this movement being against the tension of the spring 62. Said lever 64, connected with the link BI, may be manually actuated by means of the thumb piece 66 or may be automatically actuated by imparting continued movement to the sleeve I9 to a point where the pin engages the thumb piece 66 and thus rocks the lever 88 through the power applied to the sleeve While the machine'is in operation, the driving shaft 69 and its flywheel 10 are continuously turned by the motor 61 through the speed reducing mechanism. 68, and the driven shaft H is normally stationary exceptwhen the arm 18 is raised as a result of the energizing of the solenoid 82.

The operation of the control relay mechanism will now be described.

, When the contacts 85 and 86 are engaged, a circuit is closed, this circuit including the wire 93, contacts 85 and 86, the wire 94, the solenoid winding 95 and wire 96, back to the source, thus closing the normally open contacts 91 and 98. When these contacts are closed as a result of the energizing of the solenoid 95, a circuit around the switch mechanism 85 and 86 is closed through the wire 99, switch 91, wire I00, switch IM and wire I02 through the solenoid 82 and the wire 96 to the other side of the source.

When the solenoid 82 is energized, its core is moved upwardly, thus raising the arm 18 and at the same time closing the switch mechanism I05 to close a circuit including the wires I06 ,and N0, the solenoid I01 and the wire III to the wire 96, thus energizing said solenoid I 01. The energizing of this solenoid opens the switch MI and closes the switch I08. The opening of the switch IOI .will immediately de-energize the solenoid 82 even though the contacts 85 and 86 continuein engagement. With the closing of the switch I08, a circuit including the wires 93 and 99, the contact 98, the wires I09 and H0, the solenoid winding 501 and the wires III and 96 is closed, thus continuing the energization of the winding of the solenoid I01 so long as the contacts 85 and 86 are engaged and the switches 91 and 98 are closed as a result of the continued energization of the solenoid 95. Consequently, it is immaterial how long the contacts 85 and 86 be engaged, since the circuit including the winding of the solenoid 82 will be interrupted instantly with the energizing of the solenoid I01 and this solenoid will remain energized until the contacts 85 and 86 are disengaged in a manner to de-energize the solenoid 95 and permit the interruption of the circuit to the solenoid 82 at the switch mechanism 91.

To summarize, the solenoid windings 95 and 82 will be energized with the closing of the contacts 85 and 86, and with the energizing of the solenoid 82, the solenoid I01 will be energized to interrupt the circuit to the solenoid winding 82. as the contacts 85 and 86 are engaged, the solenoids 95 and I01 will both be energized, but the solenoid 82 will continue deenergized; This results from the closing of the switch 98 by the solenoid 95 and the closing of the switch E08 by So long type, making an impression therefrom and distributing the type after the impression is made, is the same as in my Letters Patent herein referred to, and a description of this mode of operation is, therefore, not necessary since it does not in any way affect the set indicator or the justifying indicator.
